What are the new syntax features in Python 3.10?

Python 3.10 introduced several new syntax features, including structural pattern matching, parenthesized context managers, and more. Would you like to know about any specific feature?

Can you explain structural pattern matching?

Sure! Structural pattern matching allows you to match complex data structures against patterns, making it easier to write clean and readable code. It uses the match statement, similar to switch-case in other languages.

How does the match statement work?

The match statement checks a value against a series of patterns and executes the corresponding block of code for the first match. Here's a simple example:

match command:
    case 'start':
        print('Starting...')
    case 'stop':
        print('Stopping...')
    case _:
        print('Unknown command')

What are parenthesized context managers?

Parenthesized context managers allow you to use multiple context managers in a single with statement, improving readability. For example:

with (open('file1.txt') as f1, open('file2.txt') as f2):
    # process files
